no video modes listed by grub
Posted: Thu Feb 15, 2024 2:10 pm
I am trying to boot a simple unikernel on a 2016 Dell XPS. I am booting via grub 2.06. I was getting the "requested video not supported" error so I wrote a grub menuentry to list all the available video modes:
However, no video modes are listed at all!
I am booting from a USB key created using grub-mkrescue. I did not specify a --platform so it's using /usr/lib/grub/i386-pc/boot_hybrid.img
Any idea why no video modes are listed and/or what I might try to debug further?
Code: Select all
menuentry "videoinfo" {
videoinfo
sleep 10
}
